My personal favourite has to be the lash glue from MAC. However any of the more expensive kinds do the trick. You should even invest in a hair bonding solution but only if you have dark lashes because it is a dark solution. It can be easily removed with any oil-based remover. Just bear in mind that if you are going to buy the cheaper eyelashes then do not use that glue, as for some reason it does not stick at all on the cheaper eyelashes! Good luck. Indulge yourself…Stay beautiful
